A sensor apparatus for wellbore applications includes an electrical conductor extending within an armored tubular jacket to protect the electrical conductor. The electrical conductor is isolated from wellbore fluids when the sensor is placed in a wellhead flange by redundant seals such that the tubular jacket around the conductor does not provide a leak path to the surrounding subsea or surface environment. To isolate the electrical conductor, a connector housing may be provided that establishes a glass-metal seal or a PEEK-metal seal with the electrical conductor. The connector housing may be welded or otherwise sealed to a Christmas tree flange that connects to the wellhead flange. The welds and seals of the sensor apparatus may be proof tested to ensure their effectiveness before the Christmas tree flange is installed in the subsea or surface environment.

A connector housing for an electrical connector includes a receiving portion arranged inside a cavity of the connector housing. The receiving portion is adapted to receive an electrical contact terminal. The receiving portion further comprises at least one latching nose adapted to block a release movement of the electrical contact terminal upon insertion of the electrical contact terminal into the connector housing. The connector housing comprises a reinforcement element made of a material different than the material of the connector housing. Said reinforcement element is arranged on a surface of the connector housing and adapted to reinforce at least a part of the connector housing in a region around the at least one latching nose. The present disclosure further relates to a connector assembly for an electrical connector.

A junction box for an electrical connection of a photovoltaic module, comprising a plug-in module and a housing module. The plug-in module comprises a plug element and a connection element, wherein the plug element enables a plug-in connection with an external electrical connection line, and the connection element provides a connection option for an internal electrical supply line into the photovoltaic module. The housing module can be connected to, and detached from, the plug-in module and can also be attached to the photovoltaic module in order to offer protection of a connection area of the photovoltaic module against outer influences.
